Binary logistic regression identified prognostic factors, while ROC analysis evaluated the predictive efficacy of D-D, NLR, and CRP/ALB. Correlations among these markers were also analyzed.Results: Binary logistic regression showed that age, D-D, ALB, CRP/ALB, neutrophil count, lymphocyte count, and NLR were significant prognostic risk factors (P < 0.05). ROC analysis yielded AUC values of 0.683 for D-D, 0.769 for NLR, and 0.728 for CRP/ALB, with combined AUC reaching 0.803. Sensitivity and specificity were 96.6%/39.3% for D-D, 100.0%/68.9% for NLR, and 100.0%/45.9% for CRP/ALB. Spearman correlation analysis revealed positive correlations among D-D, NLR, and CRP/ALB (r = 0.367, 0.482, 0.462, p < 0.05).Conclusion: Age, D-D, ALB, CRP/ALB, neutrophil count, lymphocyte count, and NLR are significant prognostic factors for intravenous thrombolysis in AIS patients. D-D, NLR, and CRP/ALB are effective indicators for predicting prognosis, with combined prediction showing greater efficacy.Keywords: acute ischemic stroke, D-dimer, intravenous thrombolysis, lymphocyte count, neutrophil count
